????目前許多手機(jī)用戶打電話、發(fā)短信和上網(wǎng)仍需通過3G網(wǎng)絡(luò)，尚未升級到4G設(shè)備，但是韓國手機(jī)廠商三星宣布，它已經(jīng)在全球范圍內(nèi)率先研發(fā)出自適應(yīng)陣列收發(fā)器技術(shù)，可以在毫米波Ka頻段進(jìn)行通信——即所謂的5G技術(shù)基礎(chǔ)。

????這并不是說3G用戶就能一下子跳過4G。據(jù)多數(shù)分析師預(yù)測，5G網(wǎng)絡(luò)最快也要到2020年才能投入商用。“這是非常關(guān)鍵的一點(diǎn)”，邁德利環(huán)球顧問公司（Medley Global Advisors）資深電訊、媒體及技術(shù)政策總監(jiān)杰弗里?席爾瓦說道，“5G會是一個全新的技術(shù)生態(tài)系統(tǒng)，它需要一系列標(biāo)準(zhǔn)的制定，而這一過程關(guān)卡重重。由于涉及巨大的經(jīng)濟(jì)利益，5G標(biāo)準(zhǔn)制定過程會是一場拉鋸戰(zhàn)。

????鑒于此，三星宣布它在研發(fā)5G技術(shù)就不奇怪了，尤其考慮到——它雖然已經(jīng)是移動電話開發(fā)領(lǐng)域的先鋒，卻長期被廣泛視為關(guān)鍵技術(shù)的跟隨者而不是領(lǐng)導(dǎo)者?！霸?jīng)的領(lǐng)導(dǎo)者有高通（Qualcomm）、諾基亞（Nokia）、愛立信（Ericsson）甚至還有摩托羅拉（Motorola）和LG，”市場調(diào)研公司IHS Screen Digest移動通信行業(yè)分析師丹尼爾?格林森說道，“三星不愿意在技術(shù)領(lǐng)域落伍，近年來它在不斷增加網(wǎng)絡(luò)業(yè)務(wù)領(lǐng)域的布局?！备窳稚a(bǔ)充說，長遠(yuǎn)來看，5G會成為一大創(chuàng)收來源。

????如果三星在研發(fā)5G技術(shù)中扮演重要角色，就能確保在以后的所有相關(guān)專利官司中拿三星所發(fā)揮的作用來辯護(hù)，這樣就能防止今后可能遭到的專利控訴。

????5G背后的技術(shù)也意味著比目前4G長期演進(jìn)（Long Term Evolution，簡稱LTE）高出數(shù)百倍的速度，將成為現(xiàn)有網(wǎng)絡(luò)的新一代版本。同時，它也需要不同頻率的寬帶，這一點(diǎn)三星解釋為就像不斷增加的水流需要更大號的水管一樣。為了解決這一問題，三星已經(jīng)計(jì)劃在毫米波段以28GHz的頻率實(shí)施數(shù)據(jù)傳輸，1.056Gbps的數(shù)據(jù)傳輸速度可以覆蓋2公里范圍。“三星一直使用更高光譜，”格林森說，“光譜越高，信號越難穿過墻體和建筑。三星使用的頻率是28GHz，而目前的Wi-Fi使用的才2.4GHz。我們都知道Wi-Fi的覆蓋范圍有多小，但三星能將信號傳送2公里，所以前景相當(dāng)廣闊?！?/p>

????While many mobile phone users are still making calls, sending texts, and surfing the web over a 3G network and have yet to upgrade to a 4G handset, South Korean mobile phone maker Samsung says it has successfully developed the world's first adaptive array transceiver technology operating in the millimeter-wave Ka bands for communications -- a.k.a. the basis for so-called 5G.

????That doesn't mean 3G users should expect to skip 4G altogether. By most estimates 5G won't arrive until at least 2020 at the earliest. "That is the real important point here," says Jeffrey S. Silva, senior policy director for telecommunications, media, and technology at Medley Global Advisors. "There is a whole kind of technological ecosystem that goes into 5G. There are standards that need to be worked out, which is very procedural. This can be very political and even controversial as there is a lot of money at stake."

????Given that fact, it isn't surprising that Samsung announced it was working on 5G technologies, especially as the company has widely been seen as more of a follower than leader in backbone technology, even as it has moved to the forefront of mobile handset development. "The leaders have been Qualcomm (QCOM), Nokia (NOK), Ericsson, and even Motorola and LG," says Daniel Gleeson, mobile analyst for IHS Screen Digest. "Samsung has been increasing its presence on the network side of the business in recent years as it wants to move from being a minor player in the technology." He adds that 5G could become a revenue stream in the long run.

????If Samsung plays a key role in developing the 5G technology it would also ensure that it could bring up its role in any future patent court cases as well, and in this way future-proof itself against such complaints.

????The technology behind 5G also promises greater speed that could be up to several hundred times faster than the current 4G Long Term Evolution (LTE), and would be the next generation of these existing networks. It would also require a broadband of frequencies, which Samsung noted is much like increased water flow requiring a wider pipe. As a solution, Samsung has looked to implement the transmission of data in the millimeter-wave band at a frequency of 28GHz at a speed of up to 1.056 Gbps to a distance of up to two kilometers. "Samsung has used a much higher spectrum band," Gleeson says. "The higher you go the less likely that the signal can penetrate walls and buildings. Samsung is using 28GHz, whereas today's Wi-Fi uses 2.4GHz, and we know how short the range of Wi-Fi is, but Samsung was able to deliver a signal over two kilometers, so that is the start of something."
